In the final scene, Ruben is sitting on a bench in a calm city after receiving his implant surgery. At first, we hear the world the way Ruben hears it through the implants, very staticky, and harsh. The sound of children playing and church bells ringing is distorted, not sounding natural at all. The film once again uses internal sound design, but now it shows us that the "fix" Ruben was chasing doesn’t really solve his problems. Instead, it creates a different kind of discomfort.
Then, Ruben takes off the implants and everything goes silent. For the first time in the film, the silence is complete. There is no music, no noise, no distortion, just quiet. But unlike the earlier scenes, this silence doesn’t feel empty or scary. It feels peaceful, as if Ruben finally stopped fighting and allowed himself to just exist in the moment.
The camera framing also changes, Ruben now being centered in the frame, and the camera completely still. There are no quick cuts or shaky movements, it holds on him for a long time as he sits calmly and looks out at the city. The stillness of the camera matches the silence, showing us that Ruben is no longer trying to run from his situation, he's accepted it.
